Act like tiny temporary batteries that store and release energy.
To understand how any electronic gadget works, you have to grasp four fundamental "rules of the road": The "push" or pressure behind the current. Current (I): The actual flow of electricity through a path. Electronics For Dummies
This allows you to build circuits by simply plugging parts in—no messy soldering required until you’re ready. Act like tiny temporary batteries that store and
This is your "eyes" in the world of electronics; it lets you see invisible voltage and current. This allows you to build circuits by simply
The control or "braking" force that slows down the flow.
Control the flow of current so other parts don't get too much power.
Complete mini-circuits packed into a single small chip (like the famous 555 timer ). How to Start Without Getting Zapped
